TimeTree: Uncovering Value from Unexpected Use Cases

This episode explores how the TimeTree calendar sharing application discovered and capitalized on an unforeseen user behavior: fans utilizing its public calendar feature to track idol schedules for "Oshi-katsu" activities.

Initially designed for broad event announcements, TimeTree observed a surge in its use by idol groups and their fans for sharing detailed schedules, including pre-release information and concert setlists. Recognizing this unexpected use as a valuable opportunity, TimeTree developed and officially released the "Public Calendar Widget," a paid service allowing users to display their favorite idol's schedule directly on their smartphone home screens.

This case study highlights the importance of prioritizing actual customer behavior over internal assumptions, redefining existing assets to meet new needs, and fostering a responsive development cycle to transform niche user innovations into significant business growth and new revenue streams.
